Botox and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
This medication falls into category C. There are no well-controlled studies that have been done in pregnant women. Botox should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.
Botox and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed. It is not known if Botox is excreted in human breast milk or if it will harm your baby.
- Botox is an injection that your doctor will give you.
- Botox is injected into your affected muscles or skin.
- Your doctor may change your dose of Botox, until you and your doctor find the best dose for you.
- Your doctor will tell you how often you will receive your dose of Botox injections.
Indication specific dosage and administration recommendations should be followed. In treating adult patients for one or more indications, the maximum cumulative dose should generally not exceed 400 Units, in a 3 month interval.
Symptoms of overdose after Botox injection may include difficulty breathing, difficulty moving parts of the body, and weakness. These symptoms may not appear right away. Call your doctor or seek emergency medical attention right away if you experience any of these symptoms.
Botox FDA Warning
WARNING: DISTANT SPREAD OF TOXIN EFFECT
Postmarketing reports indicate that the effects of Botox and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, generalized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have an underlying condition that would predispose them to these symptoms. In unapproved uses, including spasticity in children, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and at lower doses.
